Yeonjun, the popular troublemaker guy you rejected for another guy. Which is smart and popular, Yun

Yun is your boyfriend, ya'll made a promise to watch fireworks together. But when it almost new year, you look around to find him until you saw him kissing another woman while the fireworks start to begin

You watch them silently with a pain. Menwhile Yeonjun was there right behind you

"I still remember you told me that you never want to be in relationship." He sigh and smirk.
